It’s 50 years since a human being set foot on the Moon, so there’s been a lot of reminiscing recently. There’s no doubt that journey was more than a great technological achievement. It suddenly made the distance between the Moon and the Earth seem much smaller. Human beings have imagined trips to the Moon for centuries now, but, in that “One small step for Man….” the journey became a reality.
However, the change in perspective which has impressed me even more, is one which, although it is at least as ancient as imagining Moon trips, is represented by the famous photograph taken of the Earth rising above the horizon of the Moon.
This was taken by one of the astronauts on an earlier mission. It gave a powerful and striking impression of the concepts of “Spaceship Earth”, “Blue marble” and other terms people have used to describe the Earth when seen from afar.
I got thinking of this partly because of the coverage of the moon landings, but also because I happen to be reading a book by the French philosopher, Pierre Hadot. The essay I read is about the “spiritual exercise” of the classical philosophers which involves using your imagination to make a trip up into the skies. There are two elements to this exercise. The first is referred to as the “view from on high”. Think of a time you’ve looked out over the landscape from the top of a high hill. You can see the rivers, the forests, the human habitations of individual houses, villages or towns. One of the things you get is a profound change of perspective. By seeing the greater whole, you see the contexts of the elements. You get an understanding of how there it a tree line, a level on the slopes of the mountains above which no trees grow. You can see the scale and the scope of the rivers, and maybe even see the traces of where the rivers used to run before they changed to their current paths.
Go a bit higher now and imagine one of those photos you’ve seen taken from orbiting satellites or the International Space Station and now you can see whole countries, even continents. You can see lakes which have dried up, jungles which are shrinking, deserts which are expanding.
Higher again, till you see the Earth in the distance. That beautiful, but impossibly small, “blue marble”. You see the swirls of cloud formations, the spirals of hurricanes, you see the oceans and the landmasses. You know your home is down there somewhere on the surface. You know the country of your birth is there, but unless it’s completely bounded by water, you can’t see the borders between it and any other country.
Now go higher again, and sweep out through the Solar System, off through the Milky Way, heading at the speed of thought, that speed which is not limited the way the speed of light is, and see our galaxy shrinking to a cluster of stars, a single galaxy amongst millions of others, some larger, some smaller, some about the same size as “ours”. This it the second element. The ancients called it “the cosmic voyage”. You begin to get a sense of the vastness of the universe, and of the smallness of our own little neighbourhood of planets revolving around a single star.
The Epicureans saw this as a liberation from the boundaries of terrestrial life, and a way of connecting to, and immersing yourself in, eternity and infinity. They described it as a “divine pleasure”.
The Stoics said that to find peace and serenity, you should contemplate Nature and everything you find in her; that you should explore the earth, the sea, the air and the sky “attentively”; that you should follow the Moon, the Sun and the Stars with your thought; that you should keep your feet on the ground but let your spirit soar high to discover the “universal laws” and the “powers of the universe”; and that, in so doing, you would become “citizens of the cosmos”.
How beautiful is this? How enchanting? How much more positive that Theresa May’s jibe that those who wanted to belong to more than one country were “citizens of nowhere”!
Plato said that aligning the movements of your spirit with the movements of the stars in the cosmos brought harmony and well-being. Whilst some would interpret that astrologically, I understand it as a call to realism. I see it as a counsel to live harmoniously with the natural laws, of both this planet, and of the cosmos.
Hadot stresses that this exercise can have a double effect. It can produce feelings of happiness and serenity by immersing yourself in Nature, and it can allow you to enjoy a certain distancing which lets you re-evaluate the life and judge things differently (not least by seeing them within their contexts)
Seneca said that when you see how tiny the Earth looks from Space you can see how human beings share the planet with sword and fire. He says you can see how “risible” the frontiers are, and how laughable the luxuries of the rich are.
Lucien applies this exercise in the context of time rather than space and recommends it to historians. He says that when historians take the “view from on high” they can observe with impartiality, courage and a positive regard towards everyone ie to opposing sides in conflicts. He recommends that these same values, impartiality, courage and a positive regard, also influence the way historians report “the facts”.
That reminded me of the historian, Rutger Bergman, who wrote “Utopia for Realists“. I heard him say that becoming a historian allowed him to see how nothing lasts, how great cities and civilisations come and go, and how so much in human life is an invention – money, laws, borders – and that made him optimistic because the historical perspective showed him all these things can be changed. One of his key themes in his book is the abolition of borders. He points out that passports became a common practice only after World War One, and that the only countries which had them before that were the Russia and the Ottoman Empire.
It also reminded me a book I recently purchased which describes the kings and emperors of France over the centuries. Each entry includes a map which shows the territory that king, or emperor, commanded. In the process, you see the emerging shape of the country we now call France. You can do that for any country really. We tend to forget that the modern nation states are an invention.
I love this exercise, and I think our more recent discoveries about the history of the universe, about the complexity of the cosmos, and of the complex adaptive nature of all living organisms, have revealed all the more that everything is connected and that everything changes, just as Marcus Aurelius wrote all those years ago.
